Abstract: Satisfactory or enhanced dry bond between the gypsum core of plasterboard and paper facing sheets is achieved by treatment of at least the inner faces of the paper sheets with a water soluble zirconium salt before contacting the sheets with a core slurry containing gypsum plaster and starch as a dry bond assistant. The preferred zirconium salt is zirconium acetate although other salts such as oxychloride, nitrate and sulphate can also be used. The preferred level of zirconium is from 1 to 2 g. per square meter of paper, expressed as zirconium dioxide, and excellent dry bonds are formed with as little as 0.2% starch by weight of core solids, which represents an important economy in the use of starch.

Abstract: The present invention concerns a machine for vertical movement of goods, for example, transfer of parcels from a packaging belt 15 to a loading pallet 17. In one suitable embodiment of the invention, the machine consists of a hoisting cart 2 able to move vertically on a horizontally placed travelling cart 1, on which are arranged lift forks 16 for receiving and lowering of the parcel. On the travelling cart 1 are arranged counterweights 12, which are joined by wire lines 11 to the hoisting cart 2. The counterweights 12 are chosen to be heavier than the hoisting cart 2, but lighter than the hoisting cart plus the parcel. The transmission consists of an endless V-belt drive 4, which is firmly secured to the hoisting cart 2 at 9, and which is driven by a single small electric motor 3. During the work cycles, parcels are fed from the packaging belt 15 by the lift forks 16 of the machine until they thrust against a starting pulse interrupter 5, which starts the motor 3. By virtue of the weight of the parcels, the lift forks 16 descend until they are halted by the loading pallet 17. The motor 3 then pulls the travelling cart 1 backward. Meanwhile, the parcels are stopped by support rollers 13 and end up on the loading pallet 17. At a rear position, the motor 3 undergoes pole reversal through a contactor 6. The hoisting cart 2 with the lift forks 16 is then pulled upward by the counterweights 12 until it reaches a mechanical stop 14. The motor 3 continues to work and pulls the travelling cart 1 forward until it reaches an end position interrupter 10, which stops the work cycle. The work cycle then repeats until the pallet has been loaded to the desired height. <IMAGE>

Abstract: The metal oxide and carbon is injected, using carbon monoxide as the transporting gas, via a hollow electrode, into a plasma where the metal oxide is reduced. The reduction temperature is kept high so that the formation of interstitial phases is prevented. The reactor is water cooled. Metal vapour and carbon monoxide are pushed down into the cool molten metal to prevent the melt vaporising. This is aided by the use of a protective shroud around the carbon monoxide, the lower end of which is immersed in the melt. Reversion of the reduction reaction is thus prevented.
